   HelixDB—none0/10

   HelixDB documents vector, BM25 text, and hybrid graph-filtered vector search, but there is no evidence of built-in or first-party-integrated reranking models (e.g., cross-encoder rerankers) applied to search results; the pack only covers indexing and candidate retrieval, not a reranking stage.

   • [claimed-docs] “Vector indexes rank node or edge embeddings by distance. Every definition requires a non-zero dimension and a distance metric.”
   • [claimed-docs] “Text indexes provide durable BM25 search over string properties on nodes or edges.”
   • [claimed-docs] “traverse and filter an exact candidate set before vector ranking, so results cannot escape graph or permission boundaries.”
